Abstract

The invention discloses a simple water tank liquid level photoelectric early warning device. The device comprises an alarm, a magnetic control board, a positioning sleeve, stabilizers, a mounting sleeve and a buoy assembly; the mounting sleeve is fixedly mounted at the center of the axis of the buoy assembly through a screw; the magnetic control board and the positioning sleeve are mounted in a positioning manner; a strong magnetic block is mounted on the board body of the magnetic control board; and a rod body of abuoy rod sleeves the positioning sleeve in a positioning manner; the four stabilizers are uniformly installed at the four corners of the buoy assembly; and the alarm is installed at the top of the buoy rod. The simple water tank liquid level photoelectric early warning device is suitable for water level alarm design; when the water level of sealing water is lowered, the buoy assembly descends, and when the buoy assembly descends below a critical line, a magnet triggers a magnetically controlled switch, a circuit is closed, the red light of an early warning indicator is turned on so as to realize early warning; a bottom arc-shaped buoy guarantees the overall stability when water flow floats up and down, and side buoys relieve water flow impact when the water flow moves; and the stabilizers are evenly distributed and installed at the four corners of the buoy assembly so that the floating stability of the buoy assembly can be guaranteed.

Description

technical field [0001] The invention relates to the field of liquid level alarms, in particular to a simple photoelectric early warning device for the liquid level of a water tank. Background technique [0002] There are many types of slurry pumps involved in the production process of coal preparation plants, and most of the seals of slurry pumps are mechanical seals. The mechanical seal is a vulnerable part of the pump, and the price of the mechanical seal is relatively high. There are three main reasons for mechanical seal damage: sealing surface opening, overheating, and out-of-tolerance, among which overheating is the main cause of mechanical seal damage and the main cause of other types of damage. At present, the slurry pumps using mechanical seals are equipped with sealed water tanks to cool down the mechanical seals to ensure that the temperature of the mechanical seals is within the normal range. Insufficient sealing water in the mechanical seal water tank will cau...
